My Boyfriend's Roommate

I've been dating my boyfriend for eight months now, and I'm so happy to be with him. I met him on campus (we go to the same college) and after a couple of months we started to just be together almost every minute; my friends are his friends at his dorm, and I started to just live in his room and sleep there every night. His roommate was a friend and he didn't really mind me moving in. I had a single room in a different dorm, so when my boyfriend and I got horny we'd just go to my room. But we usually slept in his room. He and I slept on the bottom bunk and his roommate slept on the top bunk.

There was one night when I woke up at maybe 3:00am or so, and my boyfriend was still sleeping next to me. I needed to go to the bathroom, but I suddenly noticed the whole bunk bed was shaking slightly and there was faint slapping noises and soft moaning coming from above me. His roommate does not strike me as someone who would risk jerking off while we were sleeping below him, so I guess he was just really horny that night, and took the chance since everyone knows that my boyfriend and I sleep pretty deeply. Anyway, since it seemed so unusual, it was interesting and kind of exciting to listen to him jerk off.

I needed to pee really bad though, so I waited until it sounded pretty quiet, and then tried to make a fair amount of noise to alert him of my 'waking up'; I didn't want to startle and embarrass him by letting him know I was listening. Then I went to the bathroom, and then started to get back in bed.

His roommate then said something like 'hey' which surprised me. I said 'oh hi' and I asked when he got back (he was not there when I had gone to sleep earlier) and then we said goodnight. I found it interesting that he talked to me when he could have been completely silent, pretending to be asleep. Maybe he was trying to find out if I knew what he had been doing.

I'm glad my boyfriend slept through the entire thing, if he knew his roommate had been masturbating right above us, it would have pissed him off so much. It was an interesting experience that I enjoyed a lot. I still kind of wish that I had said something to let his roommate know that I had been listening to him though, I wonder what he would have said?
